Radiator build quality is the best i've seen, no bent or damaged fins, perfect condition, as you should expect yet rarely see on radiators in my experience. The unit has a standard depth of 27mm however its a little taller and wider than the others i've seen. Also the end tanks are relatively small and that combined with the larger dimensions means theres much more real estate dedicated to the actual fins where all the cooling happens. Silverstone also have their own proprietary fin design, it looks great and also seems to help cooling efficiency as well, not sure how acoustics are affected if at all.

Water block looks great, pump is inaudible. Also some more unique features here, no exposed bolts on copper plate and full metal construction.

Overall just excellent build quality and engineering, the solution is a little pricey compared to others but the innovations and build quality are well worth it imho, not to mention the 5 years warranty.

The only issue i have with this product are the fans. Their lowest rated speed of 1500 RPM is always going to be too loud for a system on idle. The fans seem to spin fine at lower RPM but i could only manage it through the system fan header by setting a custom fan curve in the bios. At ~550 RPM they are barely audible, not sure why silverstone didn't setup the fans to start at this RPM, 1 star has to come off for this.

After trying 3 different AIO liquids coolers from 3 different big names and returning all of them due to poor quality control i am on the verge of becoming a fully blown silverstone fanboy, in my limited experience of AIO cooling silverstones quality is 2nd to none.

Confirmed with Silverstone technician that running the fans at lower than the rated speed wont negatively affect them. Of course you must ensure that your CPU temp stays within acceptable limits.

Pros: Brilliant cooler, aesthetically pleasing, good and sturdy materials, and the most important thing it fits the Gigabyte z77n-wifi perfectly without sitting on any transistors or anything else. Temps are incredible. Would recommend to everyone.

P.S. Initially I wanted to use my old Evo 212 but it couldn't fit because of either GPU or ram (depending on direction). Then I got a Cooler Master Seidon 120v2, but I had problems mounting it because of those damn transistors, which forced me to return it.

Cons: Fans are a bit loud even on idle. Would suggest purchasing separate PWM fans that are actually quite ( Corsair or Noctua maybe ).
